New set of PCBs

An RF-engineer from the USA was kind enough to provide me with a full set of boards for the Vector Network Analyser project. This way I don't have to send an order to ExpressPCB who otherwise offer an excellent service. The shipping costs to Europe is a is $67.00 for a 2-3 day courier, which is the only shipping option their software let me choose.

This is what the PCBs look like when you order their standard service 2-layered boards. The cost for two of these panel is around $100 and the cost for 10 panels is $333. I highly recommend you to organise a group buy or simply buy 10 panels yourself and ask if anyone needs one. New people join every month and face the same problem of how to acquire the boards.

From the top left to the bottom: two PCBs for crystal ladder IF filters, ADC PCB for chip packages with 8 leads and the resolution bandwidth filter bank switch.

On a side note: with enough people for a group buy, you may as well order ROHS silver PCBs with silk screen and solder mask. The lack of solder mask can be a bit annoying at times.
